Show original supplier description
The Ksport Slimline 3-Piston Big Brake Kit is engineered to provide enhanced stopping power for enthusiasts running aggressive wheel fitments on their 2003-2008 Toyota Corolla. This kit addresses the common issue where large aftermarket brake calipers do not fit within the limited spacing behind performance wheels. Ksport developed the Slimline Caliper, inspired by OEM single-side piston caliper thickness, to ensure compatibility with most factory wheels or those with very limited brake caliper clearance. This front big brake kit features 350mm slotted, two-piece rotors constructed from lightweight carbon steel for the brackets and the rotors themselves. The kit utilizes 3-piston calipers, maintaining a similar appearance to multi-piston calipers while offering a slimmer profile. Included are SC5 Street Pads made with NAOC Ceramic material, providing optimal braking performance for street driving and occasional track use. These pads also reduce brake dust by over 50% and minimize noise and rotor wear compared to race pads, with optimal operating temperatures between 194°F - 1022°F. Ksport Big Brake kits are built to order, with an estimated production and delivery time of 4-6 weeks. The caliper brackets are CNC machined carbon steel, allowing the system to bolt directly to the OEM caliper bracket location. For rotor customization, customers can choose between slotted or cross-drilled rotors; cross-drilled rotors are recommended for daily driven vehicles due to their cooler running temperatures, while slotted rotors are suggested for track use. A wide array of caliper color options are available, including standard painted finishes like Orange, Red, Black, and Yellow, with premium high-polish upgrades in Silver, Gold, and Titanium, as well as Glassy/Hard Anodized Colors and over 20,000 custom finishes. Fitment is crucial, and while the kit is listed for the 2003-2008 Toyota Corolla, buyers are strongly advised to confirm compatibility for their specific vehicle. Fitment Industries emphasizes that buyers should always verify fitment with their team before ordering. If a sales team member confirms fitment and the product still does not fit, returns may be accepted without restocking fees, provided the item is in like-new condition. Returns are subject to specific policies, including potential restocking fees if items show signs of use or are not returned with all original accessories.
